Description
Technical field
The invention belongs to the dyeing and finishing auxiliaries of textile product more particularly to a kind of hydrophobic type stiffening agent and preparation method thereof, make
Use method.
Background technique
Stiffening agent refers to that a kind of textile auxiliary for textile hard finishing, main function are exactly to improve outside textile
It sees, increase textile elasticity and sense of fullness, and assign substance used in textile hard stiffening property, obtained just after making textile finishing
Property, stiffening, elasticity, thick and solid feel.Its application is very wide in the textile industry, can be applied to curtain, mosquito net, luggage, work
Dress, lining cloth and non-woven fabrics, etc..
Currently, common stiffening agent product specifically includes that on the market
(1) heat curing type: such as (etherificate) melamine resin, pollopas；
(2) thermoplastics type: such as polyacrylate dispersion, poly- styryl acrylic emulsion, poly-vinegar-acrylic emulsion, polyvinyl acetate emulsion
(white glue class), polyvinyl alcohol etc.；
(3) natural class: such as starch.
Wherein, the heat curing types stiffening agent such as (etherificate) melamine resin, pollopas is low due to containing higher formaldehyde
Environmental protection standard in various countries is used by limitation.Polyacrylate dispersion, poly- styryl acrylic emulsion, poly-vinegar-acrylic emulsion etc., in raw material
It is all using anion emulsifier.And in cloth dyeing technique, the common post-finishing agent cationic after stiffening treatment process
On the high side, such as hand feeling agent etc., the polyacrylate stiffening agent of anionic property can not be same with other cationic finishing agents
Bath uses, and needs multiple process, this just affects the working efficiency of dye-works, and further increases energy consumption.In addition, this
Class stiffening agent all employs greatly N hydroxymethyl acrylamide when polymerizeing and does cross-linking monomer, and the textile after arrangement still can release
A small amount of formaldehyde equally has certain limitation.And stiffening agent made of polyvinyl alcohol, due to containing great amount of hydroxy group in molecule,
Hydrophily is strong, and the textile after arrangement gets damp again (easing back) obviously, and solution viscosity is big, can not be made into high concentration product.Starch
Stiffening agent endure with all one's will it is ineffective, be appropriate only for improve feel.
Relative to above-mentioned several stiffening agents, for polyvinyl acetate emulsion (white glue class) due to low raw-material cost, performance is excellent
More, can be obtained excellent stiffening effect in the case where dosage is less, and product itself is nonionic, applicability is wide,
Such stiffening agent has broad application prospects.
PVAC polyvinylalcohol is a kind of polymer containing great amount of hydroxy group, and hydroxyl is strongly hydrophilic group, so it is one
The water-soluble high-molecular compound of kind, ionic is nonionic.PVAC polyvinylalcohol presses alcoholysis degree, can be divided into following several
Class: complete alcoholysis (alcoholysis degree is 98~99mol%), intermediate alcoholysis (alcoholysis degree is 92~94mol%), partial alcoholysis (alcoholysis
Degree is 87~89mol%) and low alcoholysis (alcoholysis degree is 79~81mol%).Due to the PVAC polyvinylalcohol macromolecular of high alcoholysis degree
It is interior and intermolecular there is stronger hydrogen bond, its water solubility is hindered, and the ester group in low alcoholysis level PVA is hydrophobic group,
Its steric hindrance is very big, can prevent the formation of PVA intramolecular and intermolecular hydrogen bonding, promote water solubility, so alcoholysis degree is got over
Low PVA hydrophily is stronger, otherwise hydrophobicity is stronger.
The partial alcoholysis polyvinyl alcohol that polyvinyl acetate emulsion (white glue class) is under normal conditions 88mol% with alcoholysis degree
PVA (such as PVA-0588,1788,2488) be used as protecting colloid, with contain polyoxyethylated nonionic surfactant (such as alkane
Base polyoxyethylene ether (paregal O), fatty alcohol ether, isomery alcohol ether) as emulsifier, gather under conditions of initiator persulfate
It closes.
Using the polyvinyl acetate emulsion good hydrophilic property that alcoholysis degree PVA is synthesized as part material, and the nonionic in raw material
Surfactant equally has good hydrophily, if by polyvinyl acetate emulsion and organic fluorine waterproof agent one-bath finishing,
Waterproof effect is influenced, therefore, in the prior art, stiffening agent finishing technique and waterproofing agent finishing technique are divided into two procedures
It completes.In addition, will form a small amount of formaldehyde, polyvinyl acetate emulsion oxygen in oxidation containing polyoxyethylated surfactant
Also a small amount of formaldehyde can be generated after change, may be polluted the environment.
